Hi, Welcome to Health care magic forum.
As you describe, it is not the
weight loss, but may be maintaining thr weight, Any how you are in moderate weight, and you can try to increase it easily.
I advise you to consult a physician for diagnosis and treatment .
I usually prescribe to my patient with such symptoms injections of
anabolic steroid periodically.
protein supplements, enzymes, and multivitamins.
Take more of calories, fats,fries,and protein rich foods,green leafy vegetables, pulses, sprouts to have a healthy and good looking body.
Wishing for a quick and complete recovery. Thank you.
